My daughter's fiance bought one when they first came out.
It shot OK with high velocity ammo and had another spring to allow lower velocity ammo to be used.

It also had a problem keeping the slide open from slide lock. Lay it down on the bench the wrong way and the slide would slam shut.
He had to send it back for repairs and the company ended up giving him a new gun. I have not heard of any problem with the second one.

I pointed out to him while the problem were occurring that the six inch S&W Model 17 he passed on in favor of the .22 autoloader would, most likely, have shot all the ammo without problems.
"Yeah, I know," sez he.

I went back a few weeks later intending to buy the M17 myself but it was gone by then.
